A review of studies in 22 U.S. states and one Canadian province found when spending for school libraries rises, better reading scores follow. Researchers examined and summarized the results of 23 U.S. and Canadian studies mostly done in the last decade and concluded that there are positive links between library support and learning. A 2008 California study, for example, established a strong positive relationship between school library budgets and test scores in language arts and history. The findings showed socioeconomic conditions could not explain away the impact of school library programs in the states studied.
